1915 Ghadar Conspiracy

The Hindu–German Conspiracy^{(Note on the name)} was a series of plans between 1914 and 1917 by Indian nationalist groups to attempt Pan-Indian rebellion against the British Raj during World War I, formulated between the Indian revolutionary underground and exiled or self-exiled nationalists who formed, in the United States, the Ghadar Party, and in Germany, the Indian independence committee, in the decade preceding the Great War. The conspiracy was drawn up at the beginning of the war, with extensive support from the German Foreign Office, the German consulate in San Francisco, as well as some support from Ottoman Turkey and the Irish republican movement. The most prominent plan attempted to foment unrest and trigger a Pan-Indian mutiny in the British Indian Army from Punjab to Singapore. This plot was planned to be executed in February 1915 with the aim of overthrowing British rule over the Indian subcontinent. The February mutiny was ultimately thwarted when British intelligence infiltrated the Ghadarite movement and arrested key figures. Mutinies in smaller units and garrisons within India were also crushed.

Other related events include the 1915 Singapore Mutiny, the Annie Larsen arms plot, the Jugantar–German plot, the German mission to Kabul, the mutiny of the Connaught Rangers in India, as well as, by some accounts, the Black Tom explosion in 1916. Parts of the conspiracy included efforts to subvert the British Indian Army in the Middle Eastern theatre of World War I.
